No, functional groups are not covered from pages 67 to 99.

I believe all material up to page 99. I would make sure though.

Midterm Day

Hi, Chem_mod

I recall class being cancelled on the day of the 14A midterm. Will there be class this Wednesday?

Error in Entropy and Degeneracy

Boltzmann Equation:

In the course reader, it states that the larger the error in the degeneracy term (W) would lead to a smaller error in entropy (S). Can someone explain this in more depth?

Re: Lewis Acids and Bases

A Lewis Base is electron rich while a Lewis Acid is electron deficient. You would typically have to draw (or mentally picture) the lewis structures of the compounds to determine whether or not a compound is a Lewis Acid or a Lewis Base.

Polyprotic Acids Tendency

Does a polyprotic acid usually lose all of its protons in a reaction (dissociate fully) or does it depend on something such as if it is strong or weak?

Re: Reducing Acid Rain

Coal factories typically have "scrubbers" installed within their smokestacks. These "scrubbers" usually contain limestone particles. The gases from burning coal leave the factory through the smokestack and must pass through limestone chamber; in here, sulfur dioxide reacts with l...

Re: balanced reactions

The first thing you should always do in a problem is check if the equation is balanced.

Re: Bond Order and # of Electrons for stability

I agree with Alex Sun that all you need to know for question 5 is that when bond order is higher, stability is greater as well. However, in terms of electrons, I believe that stability is greater when there are more electrons that fill up the bonding orbitals (sigma and pi). Inversely, stability dec...

3.57B

This part of the problem asks for the lewis and resonance structures for the hydrogen sulfite ion (HSO3-). In the solutions manual it says that only one structure obeys the octet rule, and depicts three oxygen atoms bonded to a sulfur atom, with the single hydrogen atom bonded to one of the oxygen a...

Re: Quiz 1 Preparation #3

During lecture, Professor Lavelle used the equation Δp x Δv > h/4pi. Does this work too? I thought the equation was ΔpXΔx but he did examples using the first equation. Is there a way to get one equation from the other? Or did I just write down the wrong information? I believe you somehow wrote down...

Re: Types of Bonds

An element does not have a set "bond" that it carries around. The type of bond it has with other (or the same type) of elements will depend on its electronic interaction with the other element(s). Usually all atoms in a molecule strive for an "octect" to achieve the greatest stab...

Re: Ionization Energy vs. Threshold energy

Like Alex said, the threshold energy is associated with the amount of energy required to remove an electron from a solid (via the photoelectric effect). As specified in the course reader, ionization energy refers to the amount of energy needed to remove an electron from an atom in its gaseous phase....

Re: Finals

I don't believe so, since 14B is a whole different class. Also, on pg. 165 on our course reader, prof. Lavelle gives details on the final exam and leaves it off with:

"ENJOY YOUR BREAK

SEE YOU IN CHEM 14B :)"
